Imine formation usually occurs under mildly acidic conditions; however, no acid is addedto this reaction. What is one group present that could facilitate the necessary protontransfers for this reaction?
Useful Information: sodium metam: Commercial grade sodium metam is 33% pure sodium metam by weight and has a density of 1.2 g/mL. Hydrolysis of metam (Methyl isothiocynate) + H2S Rate constants for hydrolysis for metam (base catalyzed hydrolysis is negligible) = 300 mol -1 L. sec -1 , = 1 x 10-8 sec-1 Metam also undergoes photolysis to methyl isothiocyanate with a half-life of 1.6 hrs.

2) Another method for the above reaction starts with 4-aminophenol hydrochloride (the conjugate acid of 4-aminophenol). The treatment of this the hydrochloride salt with sodium ethanoate (acetate) buffer produces 4-aminophenol which is then able to react with ethanoic anhydride as per our method. i. Why is 4-aminophenol hydrochloride not suitable for direct reaction with ethanoic anhydride? ii. Draw a mechanism (i.e. curly arrows) showing the deprotonation of 4-aminophenol hydrochloride by sodium ethanoate to form 4-aminophenol (the free base).
